Soul Slayer 
Legendary Artifact – Equipment
Animosity for creatures (This spell costs
less to play for each creature opponents control.)
Equipped creature gets +4/+4 and gains “Whenever this creature deals damage to a creature, exile that creature then draw a card for each creature card in exile.”
Equip: Sacrifice a creature.
Notes: First thing, I know it’s a cheesy and horribly unoriginal name. But back when we played the campaign, we thought it was cool and I couldn't bring myself to change it. That being said, Soul Slayer is an intelligent and powerful sword. When a living thing is killed, its essence returns to the Vitae. Soul Slayer instead steals that essence and channels it back into its wielder. Eventually, it could effectively drain the entire pool of Vitae and end all life. It was crafted at the plan of Lord Barkus, with metal and forge provided by Hearteater and enchanted by The Hag at the cost of 100 human babies. It's current wielder is Grimtooth, son of Barkus, who has been driven mad by it and is currently completely under its control. It is instrumental in Lord Barkus plan to kill the dwarves, forever.

Jonas's Keepsake
Legendary Artifact
Whenever you discard a permanent put it onto the battlefield.
Notes: Jonas is the reason the Shroud exists. I have written a couple of chapters on his fate. He is a young boy that finds a stone with magical properties over death. His mother disappeared a few years earlier and he has been living with an alcoholic father ever since. His life is horrible, and the power that he finds in the stone makes him feel like he is in control of his life again. It's a sad, twisted story, but if anyone wants that first chapter of his life I think I would be willing to share it.
